4 Claims, 3 Drawing Figures RIFLE STOCK WITH A DETACI-IABLE SPARE MAGAZINE CONTAINED THEREIN This invention relates to a rifle which comprises a quickly detachable magazine and a butt formed with a well for receiving a spare magazine.

Rifles provided with quickly detachable magazines have the advantage that is not necessary to load individual cartridges but the empty magazine can be replaced in a single manner by a full spare magazine.

A rifle is known in which the spare magazine can be inserted into a well which is accessible from the rear end face of the butt and which can be closed by a separate hinged plate. This design has the disadvantage that the spare magazine is not sufficiently fixed in the well in the butt and causes a disturbing rattling noise when the rifle is being carried and moved. It is essential to avoid such noise in a sporting rifle. The fact that the well is accessible from the rear end face of the stock has also the disadvantage that it is not possible to provide the butt with a cap of rubber or the like elastic material although such cap is often desired and could serve also as a recoil absorber. Finally, it is difficult to open the hinged plate which closes the well and to pull out the spare magazine out of the butt to the rear when this is required because the rifleman can use only one hand for this purpose, the other hand holding the rifle near its center of gravity. The same disadvantages are inherent in another known rifle, in which the well which is formed in the butt, accessible from the rear and closed by a hinged plate receives a cartridge clip holding a plurality of cartridges rather than a bar-shaped magazine.

It is an object of the invention to eliminate these disadvantages and provide a rifle which comprises a quickly detachable magazine and in which the insertion of the spare magazine into the recess formed in the butt and the removal of the spare magazine from said well are facilitated. Another object of the invention resides in that the magazine is held in position in the well so that there will be no disturbing noise. Finally, it should be possible to provide the butt with an elastic butt cap, if desired, in spite of the fact that the butt accommodates the spare magazine.

These objects are accomplished according to the invention in that the well is formed in the butt on the righthand side thereof and is adapted to be closed by the drum-shaped magazine, which conforms to the surface of the butt and which has a spring-loaded detent device, by which it is held in position in the well. Because the well is formed on the righthand side of the butt, the rear end face of the butt remains free for the provision of an elastic butt cap. The provision of the well on that side of the butt facilitates the manipulation because the rifle is held near its center of gravity by the left hand, as a rule, so that the right-hand side of the butt is within convenient reach of the right hand. The detent device holds the magazine in position in the well formed in the butt so that the magazine cannot generate rattling noise. Because the detent device is carried by the magazine itself, it can easily be actuated when the magazine is gripped by hand and there is no need to provide any levers, springs or the like on the butt. Because the magazine closes the well and conforms to the surface of the butt, it is not necessary to provide a hinged plate, a cover or the like and there is no disturbing protruding part. Another advantage is due to the fact that the same detent device can be used to hold the spare magazine in the well in the butt and to hold the magazine in charging position adjacent to the breech of the rifle.

In a development of the invention, the detent device consists of noses, which are spring urged in an outward direction to enter detent recesses formed in the well or in a well liner and adapted to be forced back from the locking position by finer bars, which laterally protrude into access recesses formed in the butt. Hence, the finger bars can be engaged by the right hand so that these bars are forced together whereby the noses are disengaged from the detent recesses and the magazine can then be withdrawn from the butt. During this operation, it is sufficient to hold the rifle with the other hand in the usual position whereas that other hand need not perform any actuation. The magazine cannot be inadvertently pulled out of the butt because this would require an exertion of oppositely directed pressures to the finger bars on both sides. Such pressure can only be exerted if the finger bars are directly engaged by hand.

Adjacent to' the cartridge discharge opening of the magazine, a bulge forcibly engaging the uppermost cartridge may be provided in the well. As the magazine is inserted. the magazine spring is slightly prestressed so that the magazine is held by force in the well and is slightly urged out of the well when the detent device has been released. This facilitates the withdrawal of the magazine.

The subject matter of the invention is shown by way of example on the drawing, in which FIG. 1 is a side elevation showing the butt of a sporting rifle and a spare magazine inserted in said butt.

FIG. 2 is on a larger scale a transverse sectional view taken on line II-Il ofFIG. 1.

FIG. 3 is also on a larger scale a longitudinal sectional view taken on line IIIIII in FIG. 2.

A butt 1 of a sporting rifle is provided with a butt cap 2 of rubber. That cap serves also as a recoil absorber. The butt I is also provided with a cheek 3 for engagement with the cheek of the shooting rifleman. On the right-hand side of the butt, opposite to the cheek, a well 4 is formed in the butt 1 and provided with a liner 5. A spare magazine 6 can be accommodated in the well 4.

The magazine is provided with a detent device, which serves to hold the magazine 6 in position in the well 4 and in another well, not shown, which is formed in the stock of the rifle adjacent to the breech. Two bars 7 are inserted in the drumshaped magazine 6 on opposite sides thereof and are biased outwardly by respective springs 8 (FIG. 3). The forward end portion 9 of each bar 7 interlocks with an associated undercut portion formed by an oblique bore 9 of the magazine. The rear portions 17 of the bars 7 are held in a recess formed by a removable magazine end cover 10. Each bar 7 has at its forward end a nose 11 which under the action of the spring 8 snaps into a detent recess 12 formed in the well liner 5. The bars have finger bar portions 13, which are spaced behind the noses l1 and laterally protrude to some extent into access recesses 14 formed in the butt.

When both finger bar portions 13 of the spare magazine 6 are engaged by hand and these bar portions are forced together against the force of the springs 8, the noses 11 will emerge from the detent recesses 12 and the magazine can be laterally withdrawn from the butt. All these operations can be performed with one hand.

In accordance with FIG. 2, the liner 5 forms a bulge 16, which is disposed adjacent to the cartridge discharge opening 15 of the magazine 6 and bears on the uppermost cartridge 18 of the inserted magazine and forces that cartridge back to stress the magazine spring, which is not shown. As a result, the magazine is forcibly held in the well 4. Cartridge follower l9 feeds the cartridges during shooting.
